piston rings

Hello, What would the normal side clearance be on a 0.187"clupet piston ring.
Regards Graham.

Side clearance on these is very small indeed - if my memory serves me right, 0.390 should do fine. Height wise, +0.015

Thanks Peter for your reply, the dim should have read 0.187" ! don't know what I was thinking! Yet another senior moment!
I guess the clearance would be the same, what do you think?
best wishes Graham.

That did sound a bit wide for a Rom.
Yes, with an 0.187" diameter ring, the groove should be 0.190".
Just be wary - measure the ring first to be sure it is only 0.187. I did once get one a little oversize and swore a lot before I realized what was wrong!!
